Key Technologies for Anticorrosion and Reinforcement of Coastal Building Structures in Alkaline Environment

Yu, H.T., 2020. Key technologies for anticorrosion and reinforcement of coastal building structures in alkaline environment. In: Al-Tarawneh, O. and Megahed, A. (eds.), Recent Developments of Port, Marine, and Ocean Engineering. Journal of Coastal Research, Special Issue No. 110, pp. 239–242. Coconut Creek (Florida), ISSN 0749-0208.The steel structure and reinforcement concrete structure have been applied in industry architecture widely. Due to the long time exposure to the alkaline environment, the corrosion of structure could not be ignored in coastal building. The following paper attempt to analysis the chemical and physical reason of structure corrosion and evaluate the broken structure strength to figure out the key technique of anti-corrosion and strengthening steel and reinforce concrete structure. Increasing cross section area, repair concrete surface, adding protection layer and enhance structure components are four key technique for anti-corrosion and structure strength, in where the carbon fiber sheet is the most effective material for component enhance.
